strange lines in netstat output

  mailing list anymore?  (-:  SDM ]

Roughly what's happening (though some of the fine details may be wrong, as
I've never paused to figure out YP) is that gethostbyaddr() tries to bind
to YP so that it can do address-to-name translation via YP.  If that
fails, the default is to fall back on /etc/hosts.  (Using the new
resolver-based libc should give different results; you'll now see
connections to a nameserver sitting around.)  Running netstat multiple
times in rapid succession makes these entries multiply, too.
